Semen Cryopreservation and Semen Quality in Transfeminine Adolescents Prior to Hormone Therapy.
Article in Journal of the Endocrine Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Some transgender individuals wish to become biological parents in the future and transfeminine persons may be offered cryopreservation of semen before starting hormone therapy. However, there is a lack of knowledge about semen cryopreservation outcomes among transfeminine adolescents seeking gender-affirming care. Objective: To investigate transfeminine adolescents who decide for or against semen cryopreservation. Methods: This is a retrospective observational national cohort study of 58 transfeminine individuals aged <18 years, assessing clinical data, semen parameters, and reproductive hormone levels. Results: Among the 58 individuals, 23 (39.7%) opted for semen cryopreservation and successfully collected a semen sample. They were older and more advanced in pubertal development compared with those who did not: median age was 16.4 years (range, 13.7-19.4) vs 15.8 years (11.7-17.9); Tanner stage G5 (4-5) vs G3 (2-4); and testis volume 20 mL (15-25) vs 8 mL (3-20). Among 17 individuals with no prior hormone therapy, the median sperm concentration was 11.1 × 10 Conclusion: The percentage of adolescents opting for semen cryopreservation was comparable to other countries with a publicly financed national healthcare system. Overall, semen quality was impaired.
